Yes, I've noticed how small the whole education community is at the moment - but think of how huge education is globally on the net! Just on maths, the main Mathematics community on G+ has 200,000 members, my own blog over 50,000 followers. Before I promote a mass migration, I would like to see at least a structure that people can see.
I also think that Education is the biggest under-monetized sector in the world - compared to people blogging about money and health, educators have little earning potential from advertisers. I've been seeking a way to micropay educators for 20 years - the tech is now here!
Gotta go to work now, back later.
I think we need @mathworksheets to become math-trail.
